GUARD AND STOP FOR IRONIN MACHINES.

Application filed Kay 8, 1926. 1 Serial No. 107,736.

This invention relates to a guard and stop for ironing machines, andwhile I haveshown myinvention in-connectionwlth av particular type ofironing machine I would have it understood that my invention 1s ap- Withbut slight modification.

- The primary object of the invention is toinvention consists in certainnovel features of construction and combinations and arrangementsof partswhich will be more fully hereinafter described and pointed out in theclaim.

In the accompanying drawings- Figure 1 is aviewin end elevation of aironing machine equipped with my improvements; o

' Figure 2 is a view infrontelevation;

Figure 3 is an end view opposite the end view shown in Figure 1 with aportion in section; a v

Figure 4 is a fragmentary View infront elevation, showing the parts in,a different position from that illustrated in Figure 2.

1 represents the frame of the ironing machine, and 2 the pivoted framewhich supports the roll 3. 4 represents the shoe of the iron, thesurface of which is concentric with that of the roll so that when thematerial is passed between the roll and the shoe it' is ironedin theordinary manner. a V I I have illustrated in dotted lines in Figure 1 astandard type of power transmission to the ironing roll which consistsof an electric motor 6'which drives. a gear train-7 to drive a shaft 8and bevel gears 9, one of which is directly connected to the roll 3.

10 represents a fixed contact and 11 a movable contact which is securedto a spring contact arm 12. 13 is 'a bell crank lever, the

lower member of which is adapted to be moved to the right of Figure 1 bythe oper-- ators foot to move the other member of said bell crank leverdownwardly and force the contacts 10 and 11 together, overcoming thetension of the spring contact arm 12.

The bell crank lever 13 is secured to a shaft 14 which carries an arm15, andthis common with ordinary ma- I porting bracket 24. This magnet27. One terminal being also connected by a arm '15 at its free endcarries a finger 16 which isadapted to engage a'catch 17 so as to holdthe contacts 10 and 11 together when the bell crank lever is moved tostarting position.

18 represents the sourc-e of electricity, one

terminal of which is connected by-a wire 19 i with contact 10 The otherterminal is oon nected by a wire 20 with one terminal 21 of motor 6. Theother spring contact arm 12. l

Thecatch. 1 7 above referred to is gravity operated and ispivotallyconnected to a supsupports a pivoted armature 25 connected by a link 26with the catch 17. Above the armature 25 I have indicated an electroofthis magnet c5 I a terminal of the ;motor 6 15 connected by a wire 23with the bracket 24- also 27 is connected by a wire 28 with a source ofelectricity 29, said source of electricity wire 30 with a contact 31,ona fixed plate 32. Another contact 33 on the fixed plate 32 is connectedby a wlre 34 with'the-other terminal of the magnet 27, a

34 represents my improved guard, which is m the form of a plate extendinthe shoe 4 and projecting forwardy over a portion of the roll 3. Thisplate has an upwardlyturnedforward free edge 35 and has flanges 36 atits ends, saidflanges being pivotallyconnected to the shoe,-a's shown at37. C011 springs 38 connect the flanges 36 with the ends of the shoe 4and serve to, hold theguard in normal position.

A rod 3,9 is pivotally connected to one of 'the flanges 36, as shown at40, and projects through the plate 32, and carries a U-shaped contact 41at its lower end so'that when the free end of the guard 34 is movedupwardly this contact 41 will be moved upwardly to engage both of thecontacts. 31 and 33 and close the circuit between the source ofelectricity 29 andthe electromagnet 27. When this magnet 27 is energizedit will draw the shown in Figure 1, the operator passes the article tobe ironed over the roll 3-When above to the posij tive to the shoe 4,the starting bein accomlished by the movement of the bel crank ever 13to close the circuit through the contacts 10 and 11 to the motor 6. Ifthe operators hands should move too'far over the roll 3 they would comein contact with the guard 34 and elevate the latter. The upward movementof this guard 34 will through the medium of the parts above describedenergize the ma net 27 to elevate the catch 17 and immedlately stop theoperationof the machine, thus preventing any possibility of the operatoraccidentally burning her hands b contact of the shoe. Various slig tchanges and alterations might be made in the general form of the partsdescribed without departing from the invention and hence I do not limitmyself to the precise details set forth but consider "myself at libertyto make such slight chan es and alterations as fairly fall within t espirit and scope-of the appended claim;

I-claim:

' In combination with an ironing machine projecting above having a rolland a shoe, an'electric motor transmitting motion to the roll, a springcontact arm having a contact thereon, [a

fixed contact, said contacts included in an electric circuit with themotor and a source of a bell crank lever adaptelectricity supply, edwhen moved in one direction to bend the spring contact arm so as toswing the con-. tacts together and close the circuit to the motor, anarm fixed to move with .the bell crank lever, a pivoted catch engagingsaid arm and holding the parts in operative position, a guard supportedon the shoe and the roll, an electromagnet adapted when energized 'tocause the catch to be moved to release the arm and permit thefirst-mentioned contacts to be separated by the movement of the springcontact arm,

and circuit closing means includedin circuit with the magnet and asource of electr1c1ty, sald circuit closing means being operated by theupward movement of the guard.
